Description

Technical Field

[0001] The utility model relates to the technical field of alarm devices, and more specifically, to alarm equipment, safety helmets and lidar warning systems. Background Art

[0002] In the distribution operation scenario, even minor operational mistakes of the operators may cause serious safety accidents. Therefore, it is particularly crucial to regulate the behaviors of the operators. In actual construction, various monitoring devices have been used to monitor the operators at the distribution site in real time. With the necessary manual inspections, relatively sufficient supervision of safety behaviors can be achieved. However, when a violation of the operation regulations is detected, it is often necessary to use the method of manual communication to feedback to the individual operator who violates the regulations, which is time-consuming and laborious, and may delay the best correction opportunity, thus leading to big mistakes.

[0003] Therefore, it is necessary to design applicable alarm equipment for distribution operators. Since it needs to be carried around, while ensuring stable operation, issues such as miniaturization and portability need to be considered. Summary of the Utility Model

[0004] The utility model aims to overcome at least one defect of the above-mentioned prior art, and provides an alarm device, a safety helmet and a lidar warning system provided with the same, which are used to solve the problem of inconvenient carrying, so as to generate alarm signals for the operators who violate the regulations in a targeted manner when equipped for distribution operators.

[0005] The first aspect of the utility model is to provide an alarm device, which includes a housing, a mounting frame, a main control board, an alarm signal generating device, a power supply device and a signal transceiver device;

[0006] The interior of the housing is hollow to form a mounting cavity, the mounting frame is arranged in the mounting cavity, and the mounting frame includes a bottom plate, a matching component and a supporting component; the matching components are arranged on both sides of the bottom plate, and the supporting components are arranged around the upper surface of the bottom plate;

[0007] The mounting frame is connected to the housing through the matching component, the supporting component is used to support and fix the main control board and keep a gap between the main control board and the top of the housing. A hollow position is formed in the middle of the bottom plate, and the power supply device is placed in the hollow position. The upper surface of the power supply device abuts against the main control board, the lower surface of the power supply device is supported by the bottom of the housing, and the power supply device is electrically connected to the main control board;

[0008] The alarm signal generating device and the signal transceiver device are both arranged on the main control board. The alarm signal generating device and the signal transceiver device are electrically connected. The signal transceiver device is used for receiving and transmitting signals. The alarm signal generating device is controlled by the signal transceiver device to switch between an on state and an off state.

[0009] In this solution, the installation frame is fitted on both sides of the installation cavity, which can provide good structural stability based on the housing itself. Furthermore, the support component provides a reliable support for the main control board. Since there is a reserved space between the main control board and the top of the housing, it is convenient to layout the alarm signal generating device, and it helps to accelerate the heat dissipation of the main control board. The height space between the main control board and the bottom of the housing and the limiting of the length and width directions of the power supply device by the hollow position can realize the stable power supply device in three-dimensional space. At the same time, the main control board and the power supply device are compactly arranged up and down, reducing the overall size of the alarm device and improving the portability of the alarm device. When the operator carries the alarm device, the alarm device emits an alarm signal through the on state of the alarm signal generating device, thereby alerting unsafe operators or supervisors, so that the corresponding operators can immediately stop unsafe operation behaviors.

[0010] In some embodiments of the present invention, the alarm signal generating device includes one or more of an optical signal generating device, a vibration signal generating device, and a sound signal generating device.

[0011] The optical signal generating device and the sound signal generating device of this solution are convenient for attracting the attention of supervisors, thereby using the supervisors to immediately warn the illegal operators. In addition, the vibration signal generating device and the sound signal generating device can also immediately alert the illegal operators themselves, so that they can immediately correct their unsafe operation behaviors by themselves and avoid the continuous development of illegal behaviors.

[0012] In some embodiments of the present invention, the optical signal generating device is arranged on the upper surface of the main control board, and a light transmission hole is provided on the upper surface of the housing. The position of the optical signal generating device corresponds to that of the light transmission hole.

[0013] In some embodiments of the present invention, the vibration signal generating device and / or the sound signal generating device are respectively arranged on any one side of the upper surface and the lower surface of the main control board.

[0014] This solution optimizes the power supply circuit layout of the sound signal generating device and the vibration signal generating device through an up-and-down layout method, avoiding the complexity of the electrical circuits on the main control board. In addition, since the operation of the sound signal generating device also needs to be realized based on vibration, the up-and-down layout can also reduce the mutual interference between the vibration signal generating device and the sound signal generating device when they are in the starting state, and can make the vibration forces received by the upper and lower surfaces of the main control board balanced, thereby improving the structural stability of the overall alarm device.

[0015] In some embodiments of the present utility model, a support member is provided on the inner surface of the bottom of the housing, and the support member supports the power supply device and leaves a gap between the power supply device and the inner surface of the housing.

[0016] This solution provides space for the air circulation on the surface of the power supply device through the gap between the power supply device and the inner surface of the housing. On the one hand, the power supply device conducts heat through contact with the housing, and on the other hand, it also assists in heat dissipation through air circulation.

[0017] In some embodiments of the present utility model, the support member is a plurality of convex beams arranged at intervals.

[0018] This solution provides a uniform supporting force for the power supply device through the convex beams arranged at intervals. While providing an air circulation space for the surface of the power supply device through the interval space, it also enables the power supply device to be reliably supported and limited.

[0019] In some embodiments of the present utility model, the fitting member is provided with a first groove structure, and the inner surfaces of the housing on both sides of the installation cavity are provided with first protruding members, and the first groove structure is fitted with the first protruding members; and / or, the fitting member is provided with second protruding members, and the inner surfaces on both sides of the housing are provided with second groove structures, and the second protruding members are fitted with the second groove structures.

[0020] This solution improves the connection strength between the installation frame and the housing through the fitting of the groove structure and the protruding member, and further improves the installation stability of the main control board, the alarm signal generating device, and the power supply device, thereby ensuring the long-term stable operation of the alarm device.

[0021] In some embodiments of the present utility model, the housing includes a cover body and a cavity portion with a front opening, the cover body is used to cover the opening, and the internal space of the cavity portion is used to form the installation cavity.

[0022] This solution easily seals the installation cavity through the cooperation between the cavity portion and the cover body, thereby achieving the effects of waterproofing and dustproofing for the interior of the installation cavity. At the same time, it also simplifies the overall structure of the alarm device and facilitates the loading and unloading of the alarm device.

[0023] In some embodiments of the present utility model, the cover body and the installation frame are integrally provided.

[0024] This solution can improve the limiting effect on the installation frame through the fitting members on both sides of the cover body and the installation frame. When the cover body covers the opening of the cavity portion, it forms an integral body with the housing, further improving the connection strength between the installation frame and the housing. At the same time, it also improves the loading and unloading convenience of the alarm device again.

[0025] In some embodiments of the present utility model, an external connection component for connecting external objects is further provided on the surface of the housing.

[0026] The alarm device of this solution is arranged on the surface of the human body or the safety helmet through the external connection component, facilitating the supervisor to perceive the alarm signal emitted when the alarm signal generating device is activated. Thus, both the operator and the supervisor can immediately perceive the illegal operation behavior based on the alarm device, shortening the time to discover unsafe operation behaviors and reducing the probability of missed alarms.

[0027] Preferably, the external connection component is arranged around the lower surface of the housing.

[0028] When the alarm device of this solution is arranged on the surface of a safety helmet or a medium such as a human arm through the external connection component, the alarm device can be significantly exposed in the supervisor's field of vision. Thus, the supervisor can more easily detect the alarm signal.

[0029] In some embodiments of the present utility model, the external connection component includes a plurality of buckle structures for buckling a belt-shaped object.

[0030] Preferably, each buckle structure includes two L-shaped limiting rods. One end of each of the two L-shaped limiting rods is respectively connected to the surface of the housing, and the other ends of the two L-shaped limiting rods face each other and have a gap.

[0031] This solution forms a frame-shaped buckle structure with a notch by a pair of relatively arranged L-shaped limiting rods, facilitating a belt-shaped object such as an elastic band to pass through the notch and penetrate the frame-shaped buckle structure to connect with the alarm device. Thus, the alarm device is tightly connected to a medium such as a safety helmet or a human arm based on a belt-shaped object such as an elastic band.

[0032] Furthermore, the lower surface of the housing is a lower arc surface.

[0033] The lower arc surface of this solution is easily matched and attached to the upper arc surface on the surface of a safety helmet or a human arm, improving the bonding strength between the alarm device and the carrying medium. In addition, since the contact area between the alarm device and the carrying medium increases, the vibration signal emitted by the alarm signal generating device can be more easily sensed by the human body.

[0034] The second aspect of the present utility model is to provide a safety helmet, including a helmet body and the alarm device described above. The helmet body is provided with a connecting member, and the alarm device is detachably connected to the connecting member.

[0035] The safety helmet of this solution can activate the alarm signal generating device when the wearer exhibits unsafe operation behaviors, thereby alerting the corresponding operators and supervisors to immediately stop the unsafe operation behaviors. In particular, when the alarm signal generating device includes an optical signal generating device, a vibration signal generating device, and a sound signal generating device, the generated optical signal and sound signal can cause the supervisor to detect the unsafe operation behavior, while the vibration signal and sound signal can attract the attention of the operator himself, thus significantly improving the timeliness and effectiveness of the supervision of unsafe operation behaviors.

[0036] The third aspect of the present utility model is to provide a lidar warning system, including a lidar monitoring device and the alarm device described above;

[0037] The lidar monitoring device includes a housing, a camera device, a lidar, a main control device, a signal transceiver antenna, and a power supply device;

[0038] The interior of the housing is hollow to form a receiving cavity. A partition connected to the housing is provided in the receiving cavity. The partition divides the receiving cavity into a lower installation cavity and an upper installation cavity. The partition is provided with a notch that communicates the lower installation cavity and the upper installation cavity;

[0039] The camera device, the lidar, and the power supply device are all arranged in the lower installation cavity. The camera device and the lidar are both electrically connected to the power supply device. The position of the power supply device corresponds to the notch;

[0040] The main control device is arranged in the upper installation cavity. The wire of the main control device is electrically connected to the power supply device through the notch;

[0041] An assembly hole communicating with the upper installation cavity is provided on the surface of the housing. The signal transceiver antenna is assembled in the assembly hole, and the signal transceiver antenna is electrically connected to the main control device;

[0042] The camera device is provided with a camera lens, and the lidar is provided with a radar probe. The front surface of the housing is provided with a first assembly port and a second assembly port. The first assembly port installs the camera lens, and the second assembly port installs the radar probe. The camera lens and the radar probe are configured in the same plane;

[0043] Among them, the signal transceiver antenna is communicatively connected to the signal transceiver device.

[0044] In this solution, the accommodating cavity of the laser radar monitoring equipment adopts an upper mounting cavity layout and a lower mounting cavity layout, so that different electronic devices are distributed in the upper and lower mounting cavities, effectively reducing the size of the integrated laser radar monitoring equipment in the length and width plane. Among them, the main control device with a larger heat generation is placed separately in the upper mounting cavity and equipped with a first heat dissipation device to dissipate its heat, which can achieve miniaturization while ensuring that the electronic devices are cooled immediately and fully. At the same time, the miniaturized setting can reduce the power consumption of the equipment. The power supply demand can be met based on conventional energy storage batteries, which is convenient for transfer to be equipped in various power distribution work sites, and also increases the willingness of the construction party to equip with a laser radar early warning system.

[0045] In addition, the camera lens and the radar probe are placed in the same plane so that the monitoring range of the camera device is consistent with the scanning range of the laser radar. When used in the monitoring of power distribution scenarios, the power supply device collects the two-dimensional image obtained by the camera device and the three-dimensional image obtained by the laser radar, so as to accurately identify the safe distance between the operator and the live equipment and lines. When unsafe working behavior is monitored, the laser radar monitoring device sends a start signal to the signal transceiver device of the alarm device through its signal transceiver antenna, so that the alarm signal generating device electrically connected to the signal transceiver device switches to the on state. When the unsafe working behavior is monitored to stop, the laser radar monitoring device sends a shutdown signal to the signal transceiver device of the alarm device through its signal transceiver antenna, so that the alarm signal generating device of the alarm device switches to the off state. In this way, unsafe working behavior can be monitored in real time.

[0046] Compared with the prior art, the beneficial effects of the utility model are as follows: 1) by matching the mounting frame with the shell arranged on both sides of the mounting cavity, the connection strength between the mounting frame and the shell is improved, so that the alarm signal generating device, power supply device, and signal transceiver device arranged on the mounting frame are all stably supported. In addition, the power supply device is limited by the space formed by the main control device, the mounting frame, and the bottom of the shell, thereby reducing the shaking of the power supply device inside the shell, and also reducing the reserved space between the power supply device, the main control device and the shell, so that the overall structure of the alarm device is compact, promoting miniaturization and portability, and then adapted to power distribution operators, so as to achieve targeted generation of alarm signals for those who do not perform normal operations; 2) a laser radar early warning system is formed by the alarm device and the laser radar monitoring device, in which the laser radar monitoring device can accurately identify the safe distance between the operator and the live equipment and lines, reduce the probability of false alarms and missed alarms of unsafe operations, and can stop unsafe operations in time through the alarm device.

DETAILED DESCRIPTION

[0057] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0058] Embodiment 1

[0059] As Figures 1-5 shown, this embodiment provides an alarm device, which includes a housing 100, a mounting frame 200, a main control board 300, an alarm signal generating device, a power supply device 500, and a signal transceiver device 600;

[0060] The interior of the housing 100 is hollow to form an installation cavity. The mounting frame 200 is arranged in the installation cavity. The mounting frame 200 includes a bottom plate 210, a fitting member 220, and a supporting member 230. The fitting member 220 is arranged on both sides of the bottom plate 210. The supporting member 230 is arranged around the upper surface of the bottom plate 210. The bottom plate 210 is supported by the bottom of the housing 100;

[0061] The mounting frame 200 is connected to the housing 100 through the fitting member 220. The supporting member 230 is used to support and fix the main control board 300 and leave a gap between the main control board 300 and the top of the housing 100. A hollow position 211 is provided in the middle of the bottom plate 210 for placing the power supply device 500. The upper surface of the power supply device 500 abuts against the main control board 300. The lower surface of the power supply device 500 is supported by the bottom of the housing 100. The power supply device 500 is electrically connected to the main control board 300;

[0062] Both the alarm signal generating device and the signal transceiver device 600 are arranged on the main control board 300. The alarm signal generating device and the signal transceiver device 600 are electrically connected. The signal transceiver device 600 is used to receive and send signals. The alarm signal generating device is controlled by the signal transceiver device 600 to switch between the on state and the off state. In actual work, when in the on state, the alarm signal generating device emits an alarm signal to remind the operators and / or supervisors. When in the off state, the alarm signal generating device does not emit an alarm signal.

[0063] During specific implementation, the installation frame 200 is fitted on both sides of the installation cavity, which can provide good structural stability based on the housing 100 itself. Furthermore, the support component 230 provides a reliable support for the main control board 300. Since there is a reserved space between the main control board 300 and the top of the housing 100, it is convenient to layout the alarm signal generating device, and it helps to accelerate the heat dissipation of the main control board 300. The height space between the main control board 300 and the bottom of the housing 100, combined with the length and width direction limiting of the power supply device 500 by the hollow position 211, can realize stable limiting of the power supply device 500 in three-dimensional space. At the same time, the main control board 300 and the power supply device 500 are compactly arranged up and down, reducing the overall size of the alarm device and improving the portability of the alarm device. When in use, the alarm device is carried with the operator. When the operator has unsafe working behaviors, the signal transceiver 600 is used to receive the start signal, so that the signal transceiver 600 controls the alarm signal generating device to be powered on. At this time, the alarm signal generating device emits an alarm signal to remind the operator and / or supervisor; when the operator stops the unsafe working behavior, the signal transceiver 600 is used to receive the shutdown signal, so that the signal transceiver 600 controls the alarm signal generating device to be powered off. At this time, the alarm signal generating device stops emitting the alarm signal.

[0064] As Figure 3 shown, in order to improve the sealing effect inside the housing 100, the housing 100 includes a cover body 110 and a cavity portion 120 with a front opening. The cover body 110 is used to cover the opening, and the internal space of the cavity portion 120 is used to form the installation cavity. In this way, it can play a waterproof and dustproof effect on the inside of the installation cavity. At the same time, it also simplifies the overall structure of the alarm device and is convenient for loading and unloading the alarm device. Continuing to refer to Figure 3 、 Figure 5 , the cover body 110 and the installation frame 200 are integrally provided. Specifically, the front end portion of the installation frame 200 is fixedly connected to the cover body 110, and the rear end portion of the installation frame 200 abuts against one side of the housing 100 away from the cover body 110. At this time, with the cooperation components 220 provided on both sides of the installation frame 200, the installation cavity of the housing 100 can provide reliable limiting for the installation frame 200, further improving the connection strength between the installation frame 200 and the housing 100. At the same time, by grasping the cover body 110, the installation frame can be operated to enter and exit the installation cavity. Therefore, it further improves the loading and unloading convenience of the alarm device.

[0065] As Figure 4 、 5As shown, in order to improve the connection strength between the installation frame 200 and the two side shells 100, the cooperating component 220 is provided with a groove structure 221, and the inner surfaces of the two side shells 100 of the installation cavity are provided with protruding members 130. The groove structure 221 is engaged with the protruding members 130, thereby improving the installation stability of the main control board 300, the alarm signal generating device, and the power supply device 500, and ensuring the long-term stable operation of the alarm device.

[0066] Reference Figure 3 、 4 , the alarm signal generating device includes an optical signal generating device 410, a vibration signal generating device 420, and a sound signal generating device 430. During actual operation, when an operator has an unsafe operation behavior, in some embodiments, for example, the unsafe operation behavior is monitored in real time through a monitoring device. At this time, the signal transceiver 600 is used to receive a start signal so that the signal transceiver 600 controls the alarm signal generating device to be powered on. It is easy to understand that the optical signal and the sound signal generated by the optical signal generating device 410 and the sound signal generating device 430 respectively are convenient for attracting the attention of the supervisor, so as to instantly warn the illegal operator with the help of the supervisor; at the same time, the vibration signal generating device 420 and the sound signal generating device 430 can also instantly alert the illegal operator himself, so as to instantly correct the unsafe operation behavior by himself and avoid the continuous development of illegal behavior.

[0067] Reference Figure 1 、 Figure 3 , for the convenience of observation by the supervisor, the optical signal generating device 410 is arranged on the upper surface of the main control board 300, and the upper surface of the shell 100 is provided with a light transmission hole 140, and the position of the optical signal generating device 410 corresponds to that of the light transmission hole 140. In addition, in order to optimize the circuit layout of the electrical appliances on the main control board 300, the vibration signal generating device 420 and the sound signal generating device 430 are respectively arranged on any one side of the upper surface and the lower surface of the main control board 300. During specific implementation, reference Figure 4 , the vibration signal generating device 420 is installed on the upper surface of the main control board 300, and the sound signal generating device 430 is arranged on the lower surface of the main control board 300. Since the operation of the sound signal generating device 430 also needs to be realized based on the vibration mode, the up-and-down layout can also reduce the mutual interference between the vibration signal generating device 420 and the sound signal generating device 430 when they are in the startup state, and can make the vibration forces received by the upper and lower surfaces of the main control board 300 balanced, improving the stability of the overall structure of the alarm device.

[0068] Reference Figure 3 、 4, To accelerate the heat dissipation of the power supply device 500, a support member 150 is provided on the inner surface of the bottom of the housing 100. The support member 150 is used to support the power supply device 500 and leave a gap between the power supply device 500 and the inner surface of the housing 100. During specific operation, the gap between the power supply device 500 and the inner surface of the housing 100 provides space for the air circulation on the surface of the power supply device 500. On the one hand, the power supply device 500 conducts heat through contact with the housing 100, and on the other hand, it also assists in heat dissipation through air circulation. In some embodiments, continue to refer to Figure 3 , the support member 150 is a number of convex beams arranged at intervals. In this way, a uniform supporting force can be provided for the power supply device 500. Thus, while providing an air circulation space for the surface of the power supply device 500 through the gap space, the power supply device 500 can also be reliably supported and limited.

[0069] During specific implementation, in order to easily receive the alarm signal of the alarm device, it is usually necessary to set the alarm device on the surface of the medium, such as being bound to the surface of a human arm or a safety helmet. Therefore, an external connection component for connecting external objects is also provided on the surface of the housing 100. In a preferred embodiment, in order to make the optical signal generating device 410 provided on the top of the housing 100 easily observable by the supervisor, the external connection component is provided around the lower surface of the housing 100. At this time, the alarm device is set on the surface of a safety helmet or a human arm and other media through the external connection component, so that the alarm device is easily exposed in the supervisor's field of vision, facilitating the supervisor to detect the alarm signal.

[0070] Refer to Figure 1 , 2 , 4, in a preferred embodiment, the external connection component includes a number of snap structures 700. During specific implementation, continue to refer to Figure 1 , 2 , each snap structure 700 includes two L-shaped limiting rods 710. One ends of the two L-shaped limiting rods 710 are respectively connected to the surface of the housing 100, and the other ends of the two L-shaped limiting rods 710 are opposite and have a gap. It can be understood that a frame-shaped snap structure 700 with a notch is formed by a pair of relatively arranged L-shaped limiting rods 710, which facilitates a belt-shaped object such as an elastic band to pass through the notch and pass through the frame-shaped snap structure 700, so that the snap structure 700 can fasten the elastic band. Thus, the alarm device is attached to the surface of media such as a safety helmet or a human arm.

[0071] As Figure 3 , 4 shown, the lower surface of the housing 100 is a lower arc surface 160. The lower arc surface 160 is easily matched and attached to the upper arc surface on the surface of a safety helmet or a human arm, improving the bonding strength between the alarm device and the carrying medium. In addition, since the contact area between the alarm device and the carrying medium increases, the vibration signal emitted by the alarm signal generating device can be more easily sensed by the human body.

[0072] Example 2

[0073] As Figure 6 shown, this embodiment provides a safety helmet, including a helmet body 20 and the alarm device 10 of Embodiment 1. The helmet body 20 is provided with a connecting member 21, and the alarm device 10 is detachably connected to the connecting member 21. Specifically, with continued reference to Figure 6 , the connecting member 21 is implemented by an elastic band tied to the safety helmet 20. At this time, a buckle structure can be provided on the lower surface of the alarm device 10, such as the buckle structure 700 shown in Embodiment 1, and by buckling the buckle structure to the elastic band, the alarm device 10 can be detachably arranged on the helmet body 20. In some other embodiments, a clamping mechanism can also be provided on the surface of the alarm device 10 to clamp the connecting member 21, so as to realize the detachable arrangement of the alarm device 10 on the helmet body 20.

[0074] When in use, the safety helmet can activate the alarm signal generating device when the wearer has unsafe operation behaviors, so as to alert the corresponding operators and supervisors to immediately stop the unsafe operation behaviors. In particular, with reference to Figures 1-5 , when the alarm signal generating device includes an optical signal generating device 410, a vibration signal generating device 420 and a sound signal generating device 430, the optical signal and sound signal generated by the alarm device 10 can cause the supervisor to perceive the unsafe operation behavior. At the same time, the vibration signal and sound signal generated by the alarm device 10 can also attract the attention of the operator himself, thereby significantly improving the timeliness and effectiveness of the supervision of unsafe operation behaviors.

[0075] Example 3

[0076] With reference to Figure 7 , this embodiment provides a lidar warning system, including a lidar monitoring device 30 and the alarm device 10;

[0077] With reference to Figures 8-9 , the lidar monitoring device 30 includes a housing 31, a camera device 32, a lidar 33, a main control device 34, a signal transceiver antenna 35 and a power supply device 36;

[0078] The interior of the housing 31 is hollow to form a receiving cavity. A partition 313 connected to the housing 31 is provided in the receiving cavity. The partition 313 divides the receiving cavity into a lower installation cavity 311 and an upper installation cavity 312. The partition 313 is provided with a notch 314, and the notch 314 communicates the lower installation cavity 311 and the upper installation cavity 312;

[0079] The camera device 32, the lidar 33 and the power supply device 36 are all arranged in the lower installation cavity 311. The camera device 32 and the lidar 33 are both electrically connected to the power supply device 36, and the position of the power supply device 36 corresponds to the notch 314;

[0080] The main control devices 34 are all arranged in the upper installation cavity 312, and the wires of the main control devices 34 are electrically connected to the power supply device 36 through the notch 314;

[0081] The surface of the housing 31 is provided with an assembly hole communicating with the upper installation cavity 312, and the signal transceiver antenna 35 is assembled in the assembly hole. The signal transceiver antenna 35 is electrically connected to the main control device 34;

[0082] The imaging device 32 is provided with an imaging lens 321, and the lidar 33 is provided with a radar probe 331. The front surface of the housing 31 is provided with a first assembly port 315 and a first assembly port 316. The imaging lens 321 is installed in the first assembly port 315, and the radar probe 331 is installed in the first assembly port 316. The imaging lens 321 and the radar probe 331 are arranged in the same plane;

[0083] Among them, the signal transceiver antenna 35 is communicatively connected to the signal transceiver device of the alarm device 10.

[0084] It can be understood that the accommodation cavity of the lidar monitoring device 30 adopts the layout of the upper installation cavity 312 and the lower installation cavity 311, so that different electronic devices are distributed in the upper and lower installation cavities, effectively reducing the size of the monitoring device integrating the lidar 33 in the length and width planes. Among them, the main control device 34 with relatively large heat generation is separately placed in the upper installation cavity 312 and equipped with a first heat dissipation device for heat dissipation. While realizing miniaturization, it can ensure that the electronic devices are cooled immediately and sufficiently. At the same time, the miniaturized setting can reduce the power consumption of the device, and the power supply demand can be met based on a conventional energy storage battery, which is convenient for transfer to be equipped in each power distribution operation site, and also improves the willingness of the construction party to equip the lidar warning system.

[0085] Reference Figure 1 、 8-9. During actual operation, the camera lens 321 and the radar probe 331 are placed in the same plane, so that the monitoring range of the camera device 32 is consistent with the scanning range of the lidar 33. When used for monitoring in a power distribution scenario, the power supply device 36 collects the two-dimensional images obtained by the camera device 32 and the three-dimensional images obtained by the lidar 33, so as to accurately identify the safety distance between the operating personnel and the live equipment and lines. When an unsafe operation behavior is monitored, the lidar monitoring device 30 sends a start signal to the signal transceiver 600 of the alarm device 10 through its signal transceiver antenna 35. Thus, the alarm signal generating device electrically connected to the signal transceiver 600 switches to the on state. When it is monitored that the unsafe operation behavior stops, the lidar monitoring device 30 sends a shutdown signal to the signal transceiver of the alarm device 10 through its signal transceiver antenna 35. Thus, the alarm signal generating device of the alarm device 10 switches to the off state. In this way, unsafe operation behaviors can be supervised in real time.
